Meet Our Founder: Ray O. Cook
Ray O. Cook started his business out of his garage in 1947. His goal was to provide services centered on a strong work ethic and integrity. Soon enough, his reputation earned him work throughout the Sacramento community. He and his team worked on major buildings like the Sacramento Convention Center, Mercy General Hospital, and county administration offices. His commitment to his business never wavered, working 12-hour days up until his retirement in 1998.
2026
Today, Ray O. Cook’s business continues to be a reliable source of HVAC services in Roseville, CA, and throughout the Greater Sacramento Area. We offer a wide array of services, including HVAC installations, maintenance, and repairs. Our dedication to a strong work ethic has never wavered, and each of our employees is highly trained and certified in this type of work.
1947
When Mr. Cook began working from his garage, central heating and air conditioning were luxuries most people could not afford. However, as the popularity of central heating grew, so did Mr. Cook’s business. A small operation that began in a garage became a staple in the Sacramento community. Mr. Cook and his team took their place on the cutting edge of AC technology and repair services.

EXCELLENT Based on 2711 reviews Posted on Google Don PanecTrustindex verifies that the original source of the review is Google. My wife, Susan, and I were extremely satisfied with the professional service, attention to detail and expertise that Gino, the certified service technician from Ray O. Cook Heating and Air displayed on our service call August 4, 2026. Gino was courteous, on time, hard working and took pride in being able to thoroughly inspect and recommend needed repairs to the 4 HVac systems that provide cooling to our home. We were especially surprised to learn that Gino treats each customer’s home as if it were his own home or his mother’s home and provides a high level of service and attention to detail in all that he does. By the end of the day, after Gino had completed servicing on all 4 of our systems, Susan and I had no reservations about signing up to be Ray O Cook Service Club members and have our HVAC and Heating units routinely serviced per their annual contract. We feel very fortunate to have discovered this amazing company.Posted on Google Robert BoehmTrustindex verifies that the original source of the review is Google.

We recently had our 22 year old Rheem air conditioner/heater replaced by Ray O. Cook Heating & Air Co. The crew respond on time and did an excellent job of removing our old system & installing a new Rheem 17 Seer A/C & furnace. The crew consisted of three men (Brett, Dave & Rick). They were all very friendly, professional & helpful in answering my numerous questions. Danny in sales & the lady that set up the appointment were also very friendly & helpful. We highly recommend this company. We had our HVAC system serviced by Technician Gene Holden on July 20th 2026 and he was very professional and did a very thorough job.
